The pylorus ( /paɪˈlɔərəs/ or /pɨˈlɔərəs/; from the Greek πυλωρός, "gate guard") is the region of the stomach that connects to the duodenum (the beginning of the small intestines). It is divided into two parts:
The pyloric sphincter, or valve, is a strong ring of smooth muscle at the end of the pyloric canal which lets food pass from the stomach to the duodenum. It receives sympathetic innervation from the celiac ganglion.
Medical significance
One medical condition associated with the pylorus is pyloric stenosis.[1] In such conditions as stomach cancer, tumours may partly block the pyloric canal. A special tube can be implanted surgically to connect the stomach to the duodenum so as to facilitate the passage of food from one to the other. This tube is called a "pyloric stent."
